Hence, their assignment is of the utmost interest to obtain information on both interactions and dynamics of proteins in solution. Here, we present the synthesis of a new precursor that allows connection of leucine and valine pro-S methyl moieties to backbone atoms by linear 13C-chains. This optimized 2H/13C-labelled acetolactate precursor can be combined with existing 13C/2H-alanine and isoleucine precursors in order to directly transfer backbone assignment to the corresponding methyl groups. Using this simple approach leucine and valine pro-S methyl groups can be assigned using a single sample without requiring correction of 1H/2H isotopic shifts on 13C resonances. The approach was demonstrated on the N-terminal domain of human HSP90, for which complete assignment of Ala-β, Ile-δ1, Leu-δ2, Met-ε, Thr-γ and Val-γ2 methyl groups was obtained. Left ventricular penetrating injuries are rare but often lethal. Transport times greater than 30min have been shown to increase the injury severity; thus early recognition of cardiac tamponade, prompt pericardial decompression, and control of cardiac hemorrhage are mandatory. We retrospectively reviewed our record to include patients with penetrating trauma of the heart. Four hemodynamically unstable young male patients with left ventricular penetrating injury of the heart were referred to our unit between January 2007 and December 2015. Median time from trauma to surgery was 16min (range 14-21). A cardiorrhaphy through sternotomy with no extracorporeal support was performed. We had no in-hospital mortality. According to our experience, in patients with hemodynamic shock and penetrating cardiac injury, a timely recognition of i
